I seem only able to get the new site, despite clearing cookies. It is frustrating and inefficient. Many of the itineraries for what should be at most a 12 hour trip are for 24-31 hours, and they are not even particularly cheap for the inconvenience of spending 2 days in transit.

When I separate the segments (multiple city) search to get only the connections I will consider, I get one leg with an unusual result: F is cheaper than E.

But when I then choose economy for the second segment, there is about a $500 disparity in the (supposedly lowest---at any rate the only one displayed) economy fare available to me depending on whether I chose the E or the cheaper F for the first segment, and of course they are different buckets.

Why is this not fare fraud? Is there some rule that says if I fly F on one segment I HAVE to fly a more expensive E fare for the second segment?

To whom and how should I report it?
